Intracellular pathogens are often considered as master cell biologists. They understand the host cells perfectly and manipulate them in subtle and non-subtle ways to ensure a successful infection. A successful infection is a complicated and fascinating process that entails the entry of the pathogen, establishment and maintenance of an intracellular niche, acquisition of nutrient and development cues, replication and finally exit from the host cell. This whole sequence of events of course occurs within the contours of the host cell, utilizing the host cellular machinery and often in the face of direct counter attacking measures from the hosts.
Pathogens and host cells have co-evolved for a long time and hence the host-pathogen interface offers fascinating glimpses into the forces that have shaped the contours of pathogenesis. The broad goal of my lab is to understand the contours of these interactions at multiple levels by studying the modulation of critical host pathways by pathogens and exploiting the potential of this knowledge for drug discovery. Currently we are exploring the modulation of host trafficking pathways by two very different pathogens, namely Mycobacterium and Plasmodium, the causative agents of the deadly diseases tuberculosis (TB) and malaria. Towards this, we apply a combination of chemical genetics, quantitative image analysis and high content screening tools together with conventional cell and molecular biological approaches.
